Thanks Suzyquad, I've been looking for the elevations found on that topo sectional. According to the radar strike the aircraft was on a heading of 195 degree climbing through 5900 feet, BUT the Elevations around Lytton are 6550 & 6706 at about where that radar hit occurred and in the direction the aircraft was heading.
I think that may have some significance and probably should be checked out some more. Can you tell us where you got that sectional?
